It is not clear from the report what the problem was, either human
error or mechanical failure. Interesting that it happened the morning
after the strike, although that may have nothing whatsoever to do with
it.

It was a woman driver.

Yes, she probably turned the steering wheel the wrong way.

From the limited information in the article, it sounds like a signaller
set the wrong route and the interlocks correctly prevented any
conflicting movements. Doesn't sound like a safety issue to me.

Not according to The Standard's version, FWIW:

"There is no suggestion that the train driver involved - who behaved "by the
book" - nor the signalman in charge of that section of track were to blame
in any way."

"A fault has been found with the signalling equipment controlling the
points. Investigators were able to recreate the fault while the line was
shut down yesterday. The siding where the train changed direction had not
been used since Monday and was out of action during Tuesday's 24-hour
strike. It was the first train to use it after services started up again."

But maybe the fault that put the train there still didn't cause a
disaster due to the track being occupied?

I mean, if the train was crossing the track rather than joining it
(which it would have done), the train coming the other way would still
have to be held.

How the "wrong line" train would be signalled or tripped is another
matter I suppose.

As far as I know there are no "sidings" at Plaistow, but there is a
bay platform on the Eastbound side, requiring departing trains to
cross the eastbound track on the flat.

It shouldn't be possible to set a route from the bay platform onto the
eastbound line as the line is not bidirectional.

Leaving the bay platform, there's a short stretch wrong-way on the
eastbound track before the crossover. So the points must have been
set as if a train was entering the bay, rather than leaving it and
taking the crossover.

I believe this is the correct scenario to have triggered the level of
concern and a formal notification to RAIB.

Indeed. You would have thought the signal allowing trains out of the bay
platform would be interlocked to the points being set correctly for the
route over the crossover, wouldn't you?

Even in the presence of a fault condition (which they've apparently
admitted)?
